It's a Tumbler Batmobile built around a #8183 Racers remote control chassis. It is drivable and steerable using the remote controller. The toughest part to design was the steering linkage for the inverted front suspension. After that, everything else just kind of came together.

As you can see from the pics I posted before, the Tumbler is quite a bit larger than the 8183 chassis and there is quite a bit of slop in the steering linkage so the car is not as fast or nimble as a standard 8183 Racer. It's still drivable but the car and wheels are too heavy for the steering mechanism so it can't steer the wheels until it has enough momentum. And no it can't jump, sorry. The landing would likely break off several pieces. I'll try to shoot some footage of the linkage working later.

HAHA, sweet. Now you need to build some police cars for it to destroy. I like how loose the steering linkage is, it almost behaves like the real thing, how it kinda leans over in turns. Now you just need to build in the 'self destruct' mode and Bat-Pod ejection
